\nTo study the variation in potential drop with length of a wire for a steady current.<\/p>\n
\nApparatus. Potentiometer:<\/strong>
\nMaterial:<\/strong> A fully charged 4.5 V battery or battery eliminator, a low resistance rheostat, a voltmeter of range (0-3.0 V), an ammeter (0-3) A, a one way key, a jockey, a set square, connecting wires and a piece of sand paper.<\/p>\n
\nFor a potentiometer with wire of uniform material density and thickness (cross-sectional area) carrying a steady current, potential drop is proportional to the length of the wire.
\n
\nwhere K is the drop of potential per unit length. It is called the potential gradient.<\/p>\n

\nPlot a graph choosing a suitable scale, for the values of potential drop V along y-axis and length l\u00a0along x-axis as shown in figure.
